A Steam generator is a device used to boil water to create steam. More specifically, it may refer to:
*
Boiler (steam generator)
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central h ...
, a closed vessel in which water is heated under pressure
*
Monotube steam generator
*
Supercritical steam generator
A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.
In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator op ...
or Benson boiler, a high-pressure steam generator that operates in the supercritical pressure regime, such that no boiling takes place within it.
*
Steam generator (auxiliary boiler), a steam-powered boiler used on ships to produce a low-pressure steam, heated by a high-pressure steam supply rather than a flame.
*
Steam generator (boiler)
A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, ...
, an oil- or gas-fired boiler, based on a low-water content monotube coil.
*
Steam generator (nuclear power)
Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core. They are used in pressurized water reactors (PWR) between the primary and secondary coolant loops.
In typical PWR designs, the p ...
, a heat exchanger in a pressurized water nuclear reactor.
*
Steam generator (railroad)
A steam generator is a type of boiler used to produce steam for climate control and potable water heating in railroad passenger cars. The output of a railroad steam generator is low pressure, saturated steam that is passed through a system of pi ...
, a device used in trains to provide heat to passenger cars.
